I need recommendations as to which carb is better for dual carb setup. I a looking at a match set of Carter YF carbs or get WA1 carbs. I need to smaller air horn for my air filters. I was going to use a couple of Monojet but the won’t work with my Thickstun air cleaners.

I am running a 261 and a Thickstun dual carb intake and Fenton headers.

I think you may find the Carters are the better choice. I have a pair of WA-1s on my 235. They were considered to be a good choice, by carbking, for my engine. I've had them on my engine for a lot of years. They have proven to be a good choice. They are trouble free and were an easy set up. I haven't touched them since I put them on.

Hi 100 fires. If this is for street use then the real question is what look do you want.

A 261 has a little more cam than a normal 235, but this is not a hop up as much as a response to the extra capacity.

If you just want driveability then the Webber carter is a far superior design.
Italian castings are factory, Spanish castings are from the same tooling, Chinese copies are fakes.

If you want old school carbs then get a good carb guy to rebuild a matched pair for you.
If you want the best torque and response then use the SAE 2 size flanged 216 carbs. If you do a lot of open road driving and want more top end bias then use a matched pair of 235 SAE 3 flanged carbs.

I would go with the Webber or the SAE 2 smaller carb size for a driver unless you have done something about compression and other improvements.

Cheers Kiwi
